TECHNICAL FIELD

The invention relates to syringe carrier.

BACKGROUND

In a conventional medicament delivery device (e.g., an autoinjector), apre-filled syringe is housed in a carrier which is axially movable toachieve needle penetration in an injection site and, optionally, needlewithdrawal. A conventional carrier provides shoulders that are adaptedto engage a neck on the syringe and prevent the syringe from disengagingthe carrier. Because syringes are generally supplied with rigid needleshields covering the needle and those needle shields have a diametergreater than a diameter between the shoulders, a separate assembly stepis required—inserting the syringe in the carrier and then attaching therigid needle shield to the needle. Accordingly, there is a need for asyringe carrier which does not require this separate assembly step.

DETAILED DESCRIPTION

Generally, and applicable to all exemplary embodiments of the presentinvention, the syringe 2 comprises a barrel 2.1 and a neck 2.2 which hasa smaller diameter than the barrel 2.1. A needle 3 is mounted to theneck 2.2 and a rigid needle shield (RNS) 4 is removably arranged on theneedle 3. When coupled to the needle 3, a portion of the RNS may cover aportion of the neck 2.2, leaving a circumferential gap between thebarrel 2.1 and the RNS 4. The RNS 4 has a diameter substantially equalto the diameter of the barrel 2.1.

FIGS. 1-4 show a first exemplary embodiment of a syringe carrier 1according to the present in invention. FIG. 1 is a top view of thesyringe carrier 1 for supporting a syringe 2. FIG. 2 is a lateral viewof the syringe carrier of FIG. 1. FIG. 3 is a longitudinal section ofthe syringe carrier of FIG. 1 in the section plane A-A. FIG. 4 is aperspective view of the syringe carrier of FIG. 1 without the syringe 2.

As shown in FIGS. 1-4, the syringe carrier 1 comprises an elongate body1.1 arranged to receive the barrel 2.1. In this exemplary embodiment,the body 1.1 has a cylindrical shape with an internal diametercorresponding to the diameter of the barrel 2.1. The body 1.1 comprisesa collar 1.2 at a proximal end dimensioned to allow axial insertion ofthe syringe 2 into the syringe carrier 1 in a distal direction D.Resilient sections 1.1.1 extend distally from the collar 1.2. Distalends of the sections 1.1.1 include shoulder sections 1.4 shaped asportions of a circle arranged in a transverse plane with respect to alongitudinal axis of the carrier 1. The shoulder sections include facingsurfaces 6. When the sections 1.1.1 are in a non-deflected position, thefacing surfaces 6 may abut each other, and the shoulder sections 1.4form a circular shoulder (because the facing surfaces 6 abut each other)adapted to engage the circumferential gap between the barrel 2.1 and theRNS 4.

The syringe 2, with RNS 4 attached to the needle 3, may be loaded intothe syringe carrier 1 by sliding the syringe 2 in the distal direction Dinto the syringe carrier 2. When the RNS 4 abuts the shoulder sections1.4, additional axial force may be applied to cause the arms 1.3 todeflect radially. When the RNS 4 has bypassed the shoulder sections 1.4,the sections 1.1.1 may return to the non-deflected position, and theshoulder sections 1.4 may engage the circumferential gap between thebarrel 2.1 and the RNS 4 and prevent the syringe 2 from moving in thedistal direction D relative to the syringe carrier 1.

In an exemplary embodiment, the proximal end 1.5 of the body 1.1 may bearranged to receive a finger flange 2.3 of the syringe 2.

In an exemplary embodiment, the shoulder sections 1.4 may includeproximally-facing contoured surfaces to accommodate a proximal portionof the neck 2.2 of the syringe 2 and distally-facing planar surfaces toabut the RNS 4.

In an exemplary embodiment, viewing windows 5 may be arranged in thebody 1.1 for allowing visual access to the barrel 2.1 of the syringe 2when the syringe 2 is in the syringe carrier 2. In an exemplaryembodiment, the windows 5 are formed when cut-outs in the arms 1.3 aresubstantially contiguous when the arms 1.3 are in the non-deflectedposition (as shown in FIG. 1). A projection 1.6 may be formed aroundeach cut-out, and when the sections 1.1.1 are in the non-deflectedposition, the projections 1.6 may form an outline for the window 5. Inanother exemplary embodiment, the windows 5 may be formed in thesections 1.1.1.

FIGS. 5-8 show a second exemplary embodiment of a syringe carrier 1according to the present invention. FIG. 6 is a lateral view of thesyringe carrier 1 of FIG. 5. FIG. 7 is a longitudinal section of thesyringe carrier 1 of FIG. 5 in the section plane A-A. FIG. 8 is aperspective view of the syringe carrier of FIG. 5 without the syringe 2.

As shown in FIGS. 5-8, the syringe carrier 1 comprises an elongate body1.1 arranged to receive the barrel 2.1. In this exemplary embodiment,the body 1.1 is comprised of two resilient sections 1.1.1 which, whentogether, have a cylindrical shape with an internal diametercorresponding to the diameter of the barrel 2.1. Distal ends of thesections 1.1.1 of the body 1.1 comprise part of a collar 1.2 dimensionedto allow axial insertion of the syringe 2 into the syringe carrier 1.Resilient arms 1.3 are formed in the body 1.1. Distal ends of the arms1.3 include shoulder sections 1.4 shaped as portions of a circlearranged in a transverse plane with respect to a longitudinal axis ofthe carrier 1. The shoulder sections include facing surfaces 6. When thearms 1.3 are in a non-deflected position, the facing surfaces 6 may abutthe distal ends of the sections 1.1.1 of the body 1.1 to form a circularshoulder adapted to engage the circumferential gap between the barrel2.1 and the RNS 4.

The syringe 2, with RNS 4 attached to the needle 3, may be loaded intothe syringe carrier 1 by sliding the syringe 2 in the distal direction Dinto the syringe carrier 2. When the RNS 4 abuts proximal ends of thesections 1.1.1, the sections 1.1.1 may deflect radially. When the RNS 4has bypassed the proximal ends of the section 1.1.1, the sections 1.1.1may return to the non-deflected position. When the RNS 4 abuts theshoulder sections 1.4, the arms 1.3 may deflect until the RNS 4 bypassesthe shoulder sections 1.4. Then, the arms 1.3 may return to thenon-deflected position, and the shoulder sections 1.4 and the collar 1.2may engage the circumferential gap between the barrel 2.1 and the RNS 4and prevent the syringe 2 from moving in the distal direction D relativeto the syringe carrier 1.

In an exemplary embodiment, the proximal end 1.5 of the body 1.1 may bearranged to receive a finger flange 2.3 of the syringe 2. The proximalend 1.5 may also include a retainer element 1.7 which is adapted toprovide an abutment surface to prevent the syringe 2 from disengagingthe syringe carrier 1 in the proximal direction D.

In an exemplary embodiment, the shoulder sections 1.4 may includeproximally-facing contoured surfaces to accommodate a proximal portionof the neck 2.2 of the syringe 2 and distally-facing planar surfaces toabut the RNS 4.

In an exemplary embodiment, viewing windows 5 may be arranged in thebody 1.1 for allowing visual access to the barrel 2.1 of the syringe 2when the syringe 2 is in the syringe carrier 2. In an exemplaryembodiment, the windows 5 are formed when cut-outs in the sections 1.1.1are substantially contiguous when the sections 1.1.1 are in thenon-deflected position (as shown in FIG. 5). A projection 1.6 may beformed around each cut-out, and when the sections 1.1.1 are in thenon-deflected position, the projections 1.6 may form an outline for thewindow 5.

FIGS. 9-13 show a third exemplary embodiment of a syringe carrier 1according to the present invention. FIG. 9 is a top view of a thirdembodiment of a syringe carrier 1 for supporting a syringe 2. FIG. 10 isa lateral view of the syringe carrier 1 of FIG. 9. FIG. 11 is alongitudinal section of the syringe carrier 1 of FIG. 9 in the sectionplane A-A. FIG. 12 is a perspective view of the syringe carrier of FIG.9 without the syringe 2. FIG. 13 is another perspective view of thesyringe carrier of FIG. 9.

As shown in FIGS. 9-13, the syringe carrier 1 comprises an elongate body1.1 arranged to receive the barrel 2.1. In this exemplary embodiment,the body 1.1 is comprised of two sections 1.1.1 which, when together,have a cylindrical shape with an internal diameter corresponding to thediameter of the barrel 2.1. The sections 1.1.1 may be coupled by a sidehinge which allows the section 1.1.1 to rotate relative to each othersufficient to receive the syringe 2. Proximal and distal ends of thesections 1.1.1 include shoulder sections 1.4 shaped as portions of acircle arranged in a transverse plane with respect to a longitudinalaxis of the carrier 1. The shoulder sections include facing surfaces 6.When the sections 1.1.1 are in a closed position, the facing surfaces 6may abut each other so that the shoulder sections 1.4 form circularshoulders adapted to proximally abut a finger flange 2.3 on the syringe2 and to distally engage the circumferential gap between the barrel 2.1and the RNS 4. The facing surfaces 6 of one section 1.1.1 may includeholes 1.10 and the facing surfaces 6 of the other section 1.1.1 mayinclude pins 1.11 adapted to engage (e.g., frictionally, snap-fit, etc.)the holes 1.10 to secure the sections 1.1.1 in the closed position.

The syringe 2, with RNS 4 attached to the needle 3, may be loaded intothe syringe carrier 1 by opening the sections 1.1.1 about the hinge andplacing the syringe 2 in the syringe carrier 2. When the sections 1.1.1are closed, the pins 1.11 engage the holes 1.10, and the proximalshoulder sections 1.4 form circular shoulders adapted to proximally abuta finger flange 2.3 on the syringe 2 and the distal shoulder sections1.4 to distally engage the circumferential gap between the barrel 2.1and the RNS 4. Thus, the syringe 2 is prevented from moving axiallyrelative to the syringe carrier 1.

In an exemplary embodiment, the proximal end 1.5 may include a retainerelement 1.7 which is adapted to provide an abutment surface to preventthe syringe 2 from disengaging the syringe carrier 1 in the proximaldirection D.

In an exemplary embodiment, the shoulder sections 1.4 may includeproximally-facing contoured surfaces to accommodate a proximal portionof the neck 2.2 of the syringe 2 and distally-facing planar surfaces toabut the RNS 4.

In an exemplary embodiment, viewing windows 5 may be arranged in thebody 1.1 for allowing visual access to the barrel 2.1 of the syringe 2when the syringe 2 is in the syringe carrier 2. In an exemplaryembodiment, the windows 5 are formed when cut-outs in the sections 1.1.1are substantially contiguous when the sections 1.1.1 are in the closedposition. A projection 1.6 may be formed around each cut-out, and whenthe sections 1.1.1 are in the non-deflected position, the projections1.6 may form an outline for the window 5.

FIGS. 14-18 show a fourth exemplary embodiment of a syringe carrier 1according to the present invention. FIG. 14 is a top view of a fourthembodiment of a syringe carrier 1 for supporting a syringe 2. FIG. 15 isa lateral view of the syringe carrier 1 of FIG. 14. FIG. 16 is alongitudinal section of the syringe carrier 1 of FIG. 14 in the sectionplane A-A.

A hinge 1.9 couplingthe door 1.12 to the body 1.1 may be provided on an axis parallel to thelongitudinal axis of the syringe carrier 1 or on an axis transverse tothe longitudinal axis of the syringe carrier 1. The shoulder section 1.4includes facing surfaces 6 which abut facing surfaces 6 of the door 1.12when the door 1.12 is in a closed position (as shown in FIG. 14). Whenthe door 1.12 is in the closed position, the facing surfaces 6 may abuteach other so that the shoulder sections 1.4 on the body 1.1 and thedoor 1.12 to form a circular shoulder adapted to engage thecircumferential gap between the barrel 2.1 and the RNS 4. The facingsurfaces 6 of the door 1.12 may include holes 1.10 and the facingsurfaces 6 of the body 1.1 may include pins 1.11 (or vice-versa) adaptedto engage (e.g., frictionally, snap-fit, etc.) the holes 1.10 to securethe door 1.12 in the closed position.

The syringe 2, with RNS 4 attached to the needle 3, may be loaded intothe syringe carrier 1 by opening the door 1.12 and sliding the syringe 2into the syringe carrier 1. When the circumferential gap between thebarrel 2.1 and the RNS 4 engages the shoulder section 1.4 on the body1.1, the door 1.12 may be closed to engage the gap and prevent thesyringe 2 from moving axially relative to the syringe carrier 1.

In an exemplary embodiment, the shoulder sections 1.4 may includeproximally-facing contoured surfaces to accommodate a proximal portionof the neck 2.2 of the syringe 2 and distally-facing planar surfaces toabut the RNS 4.

In this exemplaryembodiment, the body 1.1 is comprised of two sections 1.1.1 which, whentogether, have a cylindrical shape with an internal diametercorresponding to the diameter of the barrel 2.1. The sections 1.1.1 maybe coupled together by clips. In an exemplary embodiment, a clip maycomprise a eye 1.14 on a first section adapted to engage a hook 1.13 ona second section. The eye 1.14 may have a cross-section substantiallyequal to the cross-section of the hook 1.13 such that the eye 1.14 andhook 1.13 engage in a snap-fit. Distal ends of the sections 1.1.1include shoulder sections 1.4 shaped as portions of a circle arranged ina transverse plane with respect to a longitudinal axis of the carrier 1.The shoulder sections include facing surfaces 6. When the sections 1.1.1are in a closed position, the facing surfaces 6 may abut each other sothat the shoulder sections 1.4 form circular shoulders adapted engagethe circumferential gap between the barrel 2.1 and the RNS 4. Those ofskill in the art will understand that the sections 1.1.1 may be hingedlyconnected.

The syringe 2, with RNS 4 attached to the needle 3, may be loaded intothe syringe carrier 1 by opening the sections 1.1.1 and placing thesyringe 2 in the syringe carrier 2. When the sections 1.1.1 are closed,the eyes 1.14 engage the hooks 1.13 and the shoulder sections 1.4 engagethe circumferential gap between the barrel 2.1 and the RNS 4. Thus, thesyringe 2 is prevented from moving axially relative to the syringecarrier 1.

FIG. 27 is a perspective view of the syringe carrier of FIG.24 without the syringe 2. FIG. 28 is another perspective view of thesyringe carrier of FIG. 24.

As shown in FIGS. 24-28, the syringe carrier 1 comprises an elongatebody 1.1 arranged to receive the barrel 2.1. In this exemplaryembodiment, the body 1.1 has a partially cylindrical shape with aninternal diameter corresponding to the diameter of the barrel 2.1. Thebody 1.1 may include a longitudinal slot (e.g., a cut-out) which isadapted to snap over the barrel 2.1 of the syringe 2. Proximal anddistal ends of the body 1.1 include clamps 1.15, 1.16 which are adaptedto retain the syringe 2 when in the syringe carrier 1. The distal end ofthe body 1 further includes shoulder sections 1.4 shaped as a portion ofa circle arranged in a transverse plane with respect to a longitudinalaxis of the carrier 1. The shoulder sections 14 form circular shouldersadapted to engage the circumferential gap between the barrel 2.1 and theRNS 4.

The syringe 2, with RNS 4 attached to the needle 3, may be loaded intothe syringe carrier 1 by pressing the barrel 2.1 against the clamps1.15, 1.16, causing the clamps 1.15, 1.16 to deflect and widen thelongitudinal slot in the body 1.1. When the barrel 2.1 bypasses theclamps 1.15, 1.16, the clamps 1.15, 1.16 return to their non-deflectedposition and retain the syringe 2 in the syringe carrier 1. The shouldersections 1.4 engage the circumferential gap between the barrel 2.1 andthe RNS 4. Thus, the syringe 2 is prevented from moving axially relativeto the syringe carrier 1.

In an exemplary embodiment, the proximal end may include a retainerelement which is adapted to provide an abutment surface to prevent thesyringe 2 from disengaging the syringe carrier 1 in the proximaldirection D.

FIGS. 29-33 show a seventh exemplary embodiment of a syringe carrier 1according to the present invention. FIG. 29 is a top view of a seventhembodiment of a syringe carrier 1 for supporting a syringe 2. FIG. 30 isa lateral view of the syringe carrier 1 of FIG. 29. FIG. 31 is alongitudinal section of the syringe carrier 1 of FIG. 29 in the sectionplane A-A. FIG. 32 is a perspective view of the syringe carrier of FIG.29 without the syringe 2. FIG. 33 is another perspective view of thesyringe carrier of FIG. 29.

As shown in FIGS. 29-33, the syringe carrier 1 comprises an elongatebody 1.1 arranged to receive the barrel 2.1. In this exemplaryembodiment, the body 1.1 has a partially cylindrical shape with aninternal diameter corresponding to the diameter of the barrel 2.1. Thebody 1.1 includes a collar 1.2 at its proximal end and may include alongitudinal slot (e.g., a cut-out) formed in the body 1.1 distally ofthe collar 1.2 which is adapted to snap over the barrel 2.1 of thesyringe 2. A pair of groove hinges 1.17 may be formed in the body 1.1adjacent a proximal end of the slot. The distal end of the body 1includes shoulder sections 1.4 shaped as a portion of a circle arrangedin a transverse plane with respect to a longitudinal axis of the carrier1. The shoulder sections 14 form circular shoulders adapted to engagethe circumferential gap between the barrel 2.1 and the RNS 4.

The syringe 2, with RNS 4 attached to the needle 3, may be loaded intothe syringe carrier 1 by sliding the syringe 2 through the collar 1.2 inthe distal direction D. When the RNS 4 abuts the shoulder sections 1.4,the body 1.1 may radially deflect (e.g., rotate) about the groove hinges1.17. When the RNS 4 bypasses the shoulder sections 1.4, the body 1.1may return to its non-deflected position and retain the syringe 2 in thesyringe carrier 1. The shoulder sections 1.4 engage the circumferentialgap between the barrel 2.1 and the RNS 4. Thus, the syringe 2 isprevented from moving axially relative to the syringe carrier 1.

In an exemplary embodiment, the proximal end may include a retainerelement which is adapted to provide an abutment surface to prevent thesyringe 2 from disengaging the syringe carrier 1 in the proximaldirection D.

In an exemplary embodiment, the shoulder sections 1.4 may includeproximally-facing contoured surfaces to accommodate a proximal portionof the neck 2.2 of the syringe 2 and distally-facing planar surfaces toabut the RNS 4.
